Our purpose is to test if Pluronic® fluorescent nanomicelles can be used for in vivo two-photon imaging of both the normal and the tumor vasculature. The nanomicelles were obtained after encapsulating a hydrophobic two-photon dye: di-stryl benzene derivative, in Pluronic block copolymers. Their performance with respect to imaging depth, blood plasma staining, and diffusion across the tumor vasc...

Lipase (triasilglycerol acylhydrolase, E.C, 3.1.1.3) is an enzyme can hydrolyze long chains of triglycerides[1]. a water-soluble and naturally lipase catalyze the hydrolysis ester bonds in water insoluble lipid substrate long-chain acylglycerol synthesis, diacylglycerol, monoacylglycerol, glycerol[2]. Hydrolase be used potentialy produced fatty acid which precursors chemical industry[3]. The re...

Mie lidi merupakan salah satu makanan ringan yang dijual dengan warna menarik, harganya murah sehingga digemari oleh anak-anak. Pewarna sintetis sering digunakan adalah rhodamin B. Tujuan penelitian: untuk mengetahui cara memisahkan zat B dalam mie lidi, metode analisis tepat menguji dan kadar terkandung sampel lidi. Sampel diambil di tiga sekolah kecamatan Ajibarang. Metode penelitian deskript...

the reaction of hydrogen peroxide and  pheny -9-acridinecarboxylate in the presence of rhodamin b as a fluorophore leads to the emission of either bright blue light  or bright red light, depending on the structure of fluorescer and reaction conditions. the light emitter responsible for the chemi luminescence (cl) reaction is acridone and that the blue light produced with out the fluorescers is ...

Daun ketapang mengandung senyawa tanin yang memiliki banyak gugus hidroksil sehingga mampu digunakan sebagai bio adsorben. Salah satu cara untuk diperoleh biadsorben dengan kinerja baik maka perlu dilakukan proses aktivasi. Proses tersebut dapat secara mechanochemical, ini adalah sebuah menggunakan energi mekanik mengaktifkan material dan merubah struktur. Tujuan penelitian menganalisa pengaruh...

The aims of this experimental research are to determine the optimum contact time, influence stirring against absorbing power, and adsorption capacity activated carbon corn cob pigmen Rhodamin B. This was done vary time first concentration result showed that needed B 45 minutes, rapid process way would be more biggest with big until reach were 2,2255 mg/g. value than waste sugar cane pigment 2,0...

In the recent years a significant development of investigations with regard to bioavailability of ocular drugs has been noticed. The corneal epithelial barrier is the main pathway for ocular penetration of topically applied ophthalmic drugs into the anterior chamber. To work out an in vitro model of bovine corneal epithelial primary cultures and exercise it for permeability research with lipoph...
